Music and the brain:  Hey friends, Hope you are well! For the request of some people, from time to time I'm going to update here some material from the subject I'm researching: music and the brain. ( or: how thebrain works in a musical way ). So, here it is please, some essential material for today: It's very essential to be calibrated on the central chords in the brain: G, A, D, and E. When a man is calibrated on these chords, he is getting perfectdecisions in any field in life, and so he is on the king way in any field in life. Thank you very much! Great day, Lior.
